Verifying the main.cf file

The VCS configuration file /etc/VRTSvcs/conf/config/main.cf is created during the installation process.

See Example main.cf, for clusters without the GCO option

See Example main.cf, for clusters with the GCO option

See Example main.cf for a centrally managed cluster using Cluster Management Console

The main.cf file contains the minimum information that defines the cluster and its nodes. In addition, the file types.cf, which is listed in the include statement, defines the VCS bundled types for VCS resources. The file types.cf is also located in the directory /etc/VRTSvcs/conf/config after installation.

Note the following information about the VCS configuration file after installing and configuring VCS:

• The cluster definition includes the cluster information that you provided during the configuration. This includes the cluster name, cluster address, and the names of users and administrators of the cluster.

  Notice that the cluster has an attribute UserNames. The installvcs program creates a user "admin" whose password is encrypted; the word "password" is the default password.

• If you set up the optional I/O fencing feature for VCS, then the UseFence = SCSI3 attribute that you added is present.
• If you configured the cluster in secure mode, the main.cf includes the VxSS service group and "SecureClus = 1" cluster attribute.
• The installvcs program creates the ClusterService service group and includes the following:
  • The ClusterService service group includes the IP, NIC, and VRTSWebApp resources.
  • If you configured Cluster Management Console to manage this cluster locally, the main.cf includes the VRTSWebApp resource that includes AppName = cmc attribute.
  • If you configured Cluster Connector so that Cluster Management Console can centrally manage this cluster, the main.cf includes the CMC service group.

    The CMC service group includes the ClusterConnectorConfig and Process resources.

  • The service group also includes the notifier resource configuration, which is based on your input to installvcs program prompts about notification.
  • The installvcs program also creates a resource dependency tree.
  • If you installed VCS with the Global Cluster Option, the ClusterService service group contains an Application resource, wac (wide-area connector), whose attributes contain definitions for controlling the cluster in a Global Cluster environment.

    Refer to the Veritas Cluster Server User's Guide for information about managing VCS global clusters.

Refer to the Veritas Cluster Server User's Guide and review the chapter on configuration concepts for descriptions and examples of main.cf and types.cf files for HP-UX systems.
